Abstract

Evaluation of cypermethrin 10% + indoxacarb 10% SC against fall armyworm, Spodoptera frugiperda and stem borer in maize.

Abstract

Evaluation was conducted to check the bio-efficacy of different doses of cypermethrin 10% + indoxacarb 10% SC against fall armyworm and stem borer infesting maize. Results revealed that cypermethrin 10% + indoxacarb 10% SC EC @ 2500 g a.i./ha recorded significantly least larval population (1.21 larvae/plant) and percent plant damage (6.45%) followed by lower dose of cypermethrin 10% + indoxacarb 10% SC @ 1562.5, 1250 and 1000 g a.i./ha. However, the highest larval population and percent leaf damage was recorded in the untreated control. All the chemical treatments were found numerically inferior but statistically on par with untreated control with respect to number of natural enemies such as spiders and coccinellids.
